Laser Tracking Benefits
Laser trackers are becoming an increasingly appealing alternative to a traditional fixed CMM for inspections due to their high accuracy, portable nature and flexibility to perform dimensional inspection on very large objects. This allows Tri-State Metrology to quickly and accurately perform 3D measurements of large items and even industrial infrastructure layouts such as robots, fixture depositis, framers, 7th axis systems, welding fixtures, and overhead crane systems.
Faro and leica Laser Trackers
Tri-State Metrology uses both Faro and Leica Laser Tracker systems. Both manufacturers support high accuracy long range SMR measurements that can level items to gravity or position / adjust them accordingly in 3D Space with great precision.
Laser Tracker Inspection Services Examples:
- Machine assembly and verification
- Infrastructure layout / floor marking
- Tooling certification for large equipment
- In-process inspection of large parts or parts that cannot easily be moved
- Measurement of buildings under construction or monitoring of existing structures for movement
- Calibration of robotics systems
- Leveling of rail systems (both robotic and material handling)
- Robot Cell Certification and TCP
What is a 3D Laser Tracker?
A Laser Tracker is a device that can measure larger 3D coordinates by tracking a laser beam to a retro-reflective target. In operation, the laser tracker simply measures two angles and a distance by sending a laser beam to a target. The light reflected off the target then retraces its path back to the tracker to determine the distance through an interferometer and two angles through angular encoders. The tracked target is generally a spherically mounted retro-reflector or SMR. The SMR is placed in contact with the location to be measured. The distance and two angles are enough to accurately locate the SMR. Just like a touch probe on a CMM, the SMR has a fixed radial distance from the center to the point of contact on the measured surface.
